Google will deprecate its Google Maps Data API in January, lending support instead to its popular new Google Fusion Tables API. Both store geographic data and allow developers to access it programmatically. The move to discontinue support of the Maps Data API does not affect the Google Maps API, the third version of which Google sent into production in May.

The project that runs Wikipedia has added improved mapping extensions that let you embed Yahoo or Google Maps within your Wiki pages. Special markup is translated to API calls, which keeps out JavaScript that would be required if creating maps directly.
